'TROLLEY FOR ELECTRIC RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 585,602, dated June 29, 1897. Application filed November 30, 1896. Serial No. 613,866. (No model.) Patented in Switzerland May 16, 1396, No. 12,205.

To all whom, it may concern.-

, Be it known that I, VICTOR THELIN, electrician, of Geneva, Switzerland, have invented certain new and useful Improvements in Trolleys for Electric Railways, (patented in Switzerland May 16, 1896, No. 12,205,) of which the following is a specification.

The invention relates to an improved connector intended to establish a contact between an aerial-electrical line and the circuit of a motor fixed to a car of an electrical tramway. The said connector is of great flexibility combined with the utmost security as re gards the continuity of the contact. It will be reversed automaticallywhen the car turns back.

The accompanying drawings show, by way of example, a form of execution of the invention.

Figure 1 is a side elevation of the connector bearing against an aerial wire, and Fig. 2 is a front elevation of the same connector left to itself. 7

There is secured to the roof of the car a frame A, bearing two brackets B, between which a fork O 0, provided with a pulley D,'is

pivoted. The latter is actuated by means of two ropes or chains d, one end of which is connected with the one end of a spiral spring E, the other end of which spring is secured to the frame A. The other ends of the ropes or chains 61 being fixed to the pulley D, the rotation of the latter in either direction causes the spring E to be stretched, and therefore the spring E always restores the fork C O to the vertical position when it has been de pressed, which occurs only exceptionally, when the electrical line falls in an abnormal wayfor instance, in order to pass under a bridge.

The upper part of the fork C O carries the contact-piece or bow F, pivoted to a transverse bar G. Springs I-I tend to raise the bow F to a vertical position and thus cause it to rub against the aerial line J, placed in asuitable manner, as seen in Fig. 1.

WVhen the car goes back, the bow F presses against the electrical line J, the forks O (3 yield, and the said bow F swings automatically into the position shown by dotted lines in Fig. 1, and with this movement the arms F, being at about one hundred and thirtyfive degrees to the arms 0, press the arms 0 into an inclined position until the arms F pass a vertical position, when the spring E returns the arms (J to a vertical position, causing the arms F to assume the opposite inclination adapted to the movement of the car in the opposite direction, and in consequenoe of the pulley D havinga center in line with the pivots B of the arms O the spring E acts through the ropes or chains d to bring the arms 0 vertical, because such chains or ropes cl pass in opposite directions around the pulley D.

I claim as my invention- 1. The arms 0 pivoted at their lower ends, the pulley D with its center in line with the pivots, a spring E and connections extending therefrom to opposite sides of the pulley, so that the one spring acts to swing the arms vertical, in combination with the bow F, transverse bar G, on which the bow is pivotally connected to the upper ends of the arms 0, and the springs H acting upon the bow to raise the outer portion into contact with the trolley-wire and by which the parts are caused to turn automatically into their correct position when the direction of motion of the car is reversed, substantially as specified.

2. The combination with the pivoted arms 0 and their spring E, of the bow formed of a wire extending across between the diverging arms F and pivots connecting such arms to the upper ends of the arms 0 and the springs H, for acting on the lower ends of the arms F, the angle of the arms 0, to the arms F when in use being about one hundred and thirty-five degrees, so that when a reverse movement is given to the trolley, the arms 0 will be swung down and the positions of the parts reversed, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

VICTOR THELIN.
